RECEPTACLE.

Speccation of Letters Patent.

Application sied April 21, 1910. serial No. 556,806.

To all whom 'it may concern:

Be it known that I, ROBERT Y. BRADSHAW, a citizen of the United States of America, and a resident of Chicago, county of Cook, State ofl Illinois, have invented certain new and useful Improvements in Receptacles, of which the following is a specification.

Bronze paint, las heretofore commonly prepared and placed on the market, comprises bronze powdermixed with a ljiquid vehicle, such as benzin. It has been found that such a paint deteriorates with age, the bronze losing its luster and becoming dis colored or tarnished.

j The main objects of the `present invention are to provide a receptacle in which the components of bronze paint may be stored and shipped without deterioration or leakage of either component, the receptacle being so constructed that the ultimate purchaser can easily mix the components together just prior to use.

Although the specific embodiment shown in the drawing will here be described with particular reference to its use as a receptacle for bronze paint, its general utility for storing and transporting other materials in measured quantity will be apparent.

In the drawings, Figure 1 shows, in elevation, the outer shell, the inner shell and the cover. Fig. 2 is a sectional elevation showing the shells in their normal posi-tions, and Fig. 3 is a detail, illustrating more clearly the nature of the joints at various parts of the article. f

In the construction shown, the receptacle comprises an outer shell, 1, preferably of sheet metal, with an annular shoulder 2 pressed or swaged inward near the middle of the shell. This annularshoulder forms a bearing. surfaceforffsupport for the inner shell or receptacle 3. The inner shell is of cylindrical outline with an outstanding annular shoulder 4 near its base, adapted to restl on the shoulder 3 of the outer `shell.\

An annular packing ring 5 of rubber may be interposed between the shoulders to insure a tight annular joint. The inner shell 3 has an annular off-set 6 in its top edge forming a seat for a fiat disk or closure which consists preferably of thin sheet tin and is *seatedbelow the upper edge 8 of the shell by anamount suiiicient to admit of a strong soldered connection between the edge and the disk. A'flanged cover 9 is provided for the outer shell, and is adapted to contact with the upper edge 8 of the inner shell, and when pushed downward, tends to tighten the annular joint at the packing ring 5. Cover' 9 may have a slot 10 in its flange, c0- operating with a pin or projection 11 on the outer shell to form a bayonet joint.

When this receptacle is to be used for the storage and trans ortation of the components of bronze paint, the liquid component may be placed in the inner shell 3 and there closed up tight by a soldered connection between the disk 7 and the upper edge 8 of the shell. The bronze powder may be placed in the bottom of the outer shell, and there lsealed up by slipping the inner shell 3 into position with its annular shoulder 4 in co.- operative relation with the supporting shoulder 2. Then the cover 9 is slipped into position, thetwedging action of the 'bayonet joint tightens up the 'connection between the annular shoulders. Vith this arrangement of 1- the several elements, 'the bronze powder is prevented from working upward into the annular space between the two shells, and there can be no leakage of either powder or liquid, even though the joints between the cover 9 and the other members are not absolutely tight. When the receptacle is received by `the ultimate purchaser, the cover 9 may be slipped olf, the inner shell may be removed and opened vby a cut through the thin tin disk 7, and the liquid contents may then be poured into' the bronze powder remaining in the outer shell. I.

' The fact that the powder does not have VVaccess .to the annular space between the two shells is ofadvantage to the purchaser, inasmuch as there is no danger that the powder will puif out or "spill when the cover 9 is pulled from the can.

For the convenience of the purchaser, it is preferred to provide a separate receptacle of suitable size to fit in the lower compartment as a container for the powder. This is 'shown at 12 in Fig. 2, in the form of a pasteboard carton or envelop. In the form shown, this carton comprises a pasteboard ltube with end cap 13, the diameter of the tube being such that it will readily pass the shoulder 2 of the shell 1 and it is of a height slightly less than the height of the space below the shell 3 so that it will not interfere with the seating 'of the shell 3 upon the shoulder 5. By placing the powder in theY carton, the purchaser is enabled to mix and use any part of the contents of the receptacle Without ai'ecting the usefulness of thereceptacle as a container for the remaining part of the contents. Although but one specific embodiment of this invention is herein shown, it will be understood that numerous details 4oi? the construction shown may be altered or omitted, Without departing from the spirit of this invention.

I claim: l. A receptacle, comprising an outer shell,

u a loosejoint cover therefor, a hermetically sealednner shellbelow said cover, sloping shoulder nearA its base and annular shoulders on said shells, and means coacting With said cover adapted to maintain a liquid-tight joint between said shoulders near the vbase of said inner shell.

2. A receptacle, comprising an outer shell having an annular shoulder near its middle,

a packing ring on said shoulder,'a sealed inner shell having an outstanding annular seated on said packing ring, a. loose joint cover, and means` vcoacting With said cover adapted to produce pressure on the top of said inner shell to hold it against said packing ring.

3. A receptacle, comprising an outer shell having an annular shoulder near its middle, a packing ring seated on said shoulder, a

.sealed inner shell having an outstanding ROBERT YBRADSHAW.
